aOutputs button — The Outputs button toggles between output 1 and output 2.

bOutput LEDs — The Output LEDs indicate the selected output. When an output is muted (audio and/or video) the input LED for the muted output will be off (audio and/or video).

cInput buttons and LEDs — The input buttons (1 through 4 on the MMX 42 and 1 through 6 on the MMX 62) select an input for output. The input LEDs indicate the selected input and the video and audio mutes as follows:

	Input LED indications
	Video only	Audio only	Video and
	tie	tie	audio tie
Input selected	Lit	Blinking	Lit
Audio muted	Lit	Off	Lit
Video muted	Off	Blinking	Blinking
Video and audio muted	Off	Off	Off

dConfiguration (Config) button (video and/or audio selection) — When pressed and released, the Configuration button cycles through video and audio, audio only, and video only selection.

eVideo and Audio LEDs — The Video and Audio LEDs indicate whether video, audio, or both are selected for display and/

or selection. If audio is broken away and video and audio are selected for display, the Audio LED blinks.

Front Panel Operations

Plug in all system components and turn on the input devices (such as DVD players and DSS receivers) and the output devices. Set the input devices to output video using each device’s own operating instructions.

Creating ties

A Tie is an input-to-output connection. An input can be tied to both outputs. (An output can never be tied to more than one input.)

Create video and/or audio ties using the front panel buttons as follows:

1.	Press and release the Outputs button to select the desired
	output. The LED for the selected output lights.
2.	Press and release the Configuration button as necessary
	to select either video and audio (audio follow) or video or
	audio (audio breakaway).
3.	Press and release the button for the desired input. The
	LED for the selected input lights.

NIf audio and video are tied from different inputs (audio breakaway), and if you select video and audio for display, the Video LED and the LED for the selected video input light steadily and the Audio LED and the LED for the selected audio input blink .

A tie can also be created by an RS-232 device (see chapter 4, "Remote Control").

NIf an output is muted via RS-232, pressing any input button unmutes the output.

Memory

Audio settings are saved in nonvolatile memory. When the switcher is powered off, the settings are retained. When the switcher is powered on again, the switcher recalls the connections made prior to power down and the saved settings are active. On initial power on, the switcher defaults to input 1 tied to output 1 and output 2.
